“When he sees his face in the mirror he says, ‘Mama, if only it was less swollen I wouldn’t have a problem’.”

Zoubair’s father, Abderrahmane, a taxi driver, was unable to pay for his son to fly to America for the potentially life-saving surgery.

But the Waner Foundation, a charity which helps children in need of life-changing surgeries, brought Zoubair to New York to be treated by vascular plastic surgeon Dr Milton Waner and his team at Lenox Hill Hospital in Manhattan.

Currently Zoubair has problems sleeping, eating, breathing and talking

Dr Waner, said: “He has a particularly severe venous malformation and unfortunately his malformation is not compatible with a normal lifespan.

“When I saw the video of him stunt cycling, I was absolutely horrified because any bump could result in a terminal haemorrhage.

“He could be very quickly overwhelmed and drown in his own blood.

“He has a high risk for bleeding, he has a high risk for spontaneous haemorrhage without me even touching him, so Zoubair is, I have to say, a walking time bomb, so we really have to get on and do his treatment.”
